The company is interested in Cecil because of its easy access to local highways as well as the Jacksonville area work force, company spokesman Jesse Bull said.

However, in accordance with company policy, FedEx is not releasing details while it is still in discussions about the site.

The company has long been rumored to be looking at the site, a former Navy base, which is owned by the city of Jacksonville and is being developed by Hillwood Development Co.

Hillwood was brought on board by the city in 2010, more than a decade after the Navy turned the land over to the city in 1999.

In the years following the Navy’s handoff, development was all-but-nonexistent at the site: although the area around the airstrip, which is owned by the Jacksonville Aviation Authority, attracted companies, the city-owned portion didn’t get anyone until 2006, when Bridgestone/Firestone North American Tire built a warehouse there.

More recently, Hillwood applied for permits to build a one million-square-foot warehouse at the site; its contract with the city requires it to build a 400,000-square-foot by June of this year, even if it doesn’t have a tenant.

Although that warehouse was rumored to be the possible home of a FedEx distribution center, documents filed with the city Wednesday point to another possibility.

Those documents, submitted to the Cecil Commerce Center Architectural Design Review Board, describe a 300,000-square-foot warehouse as well as a maintenance and gateway building sitting on 45.5 acres. The site would include 537 parking spots -- hundreds more than the city requires, but necessary to meet the “peak employee shift requirements” of the building’s user.

The site also includes a number of spaces for trailer parking and fuel island.

The proposed building is a “special-purpose logistic facility” that is not expected to receive “significant customer or vehicle traffic,” according to the documents.

Hillwood declined to comment on the project. Messages left with Prosser Hallock Inc., the engineering company that submitted the plans to the city, were not immediately returned.
